In this context, the notion of <jats:italic>diversity<\/jats:italic> has been proposed as a way of mitigating the side effects resulting from the specialization of recommender systems. In this paper, using a well-known recommender system that makes use of collaborative filtering in the context of musical content, we analyze the diversity of recommendations generated through the lens of the recently proposed <jats:italic>information network diversity measure<\/jats:italic>. The results of our study offer significant insights into the effect of algorithmic recommendations. On the one hand, we show that the musical selections of a large proportion of users are diversified as a result of the recommendations. On the other hand, however, such improvements do not benefit all users. They are in fact mainly restricted to users with a low level of activity or whose past musical listening selections are very narrow. Through more in-depth investigations, we also discovered that while recommendations generally increase the <jats:italic>variety<\/jats:italic> of the songs recommended to users, they nonetheless fail to provide a <jats:italic>balanced<\/jats:italic> exposure to the different related categories.<\/jats:p>","DOI":"10.1007\/s41109-022-00530-7","type":"journal-article","created":{"date-parts":[[2023,1,25]],"date-time":"2023-01-25T09:02:36Z","timestamp":1674637356000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Measuring the effect of collaborative filtering on the diversity of users\u2019 attention"],"prefix":"10.1007","volume":"8","author":[{"given":"Augustin","family":"Godinot","sequence":"first","affiliation":[]},{"given":"Fabien","family":"Tarissan","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2023,1,25]]},"reference":[{"key":"530_CR1","doi-asserted-by":"publisher","unstructured":"Abbar S, Amer-Yahia S, Indyk P, Mahabadi S (2013) Real-time recommendation of diverse related articles.
